### There is more than one element with `"banner"` role on the page

<div id="locLevel"></div>

There must be only one element with `"banner"` role used on the page

</Column>
</Row>
<Row>
<Column colLg={11} colMd={5} colSm={4} className="toolMain">

### Why is this important?

When more than one `"banner"` landmark role is used on a web page, it can confuse people who use assistive technologies that rely on this information to easily navigate the various sections in the page.

<div id="locSnippet"></div>

### What to do

* Remove `"banner"` role from all but one element. (The`<header>` element has an implicit role of banner when it is a descendent of the body element.)

For example:

<CodeSnippet type="multi" light={true}> &lt;body&gt;
	&lt;div role="banner"&gt;banner content...&lt;/div&gt;
	&lt;div role="search"&gt;Search widget&lt;/div&gt;
	&lt;div role="contentinfo"&gt;Copyright information...&lt;/div&gt;
&lt;/body&gt;</CodeSnippet>

</Column>
<Column colLg={5} colMd={3} colSm={4} className="toolLeft">
